Identification of Genetic Variants That Contribute to Keloid Formation in Families and Isolated Cases.

Keloids are scars that keep growing beyond the border of the original wound. They typically persist for several years, expand for an extensive period of time and are sometimes called benign tumors. Keloids often have a lumpy surface and are often tender, itchy or inflamed around the growing border. Keloids in most keloid patients do not run in the family. In the inheritable form of keloids it is possible that there is one major gene mutation that puts family members at risk for developing keloids. There may be other variations in the DNA (DNA makes up the chromosomes) that determine whether k…
